Mopar 68026995AB Valve-EGR

NOx are formed in engines when oxygen and nitrogen mix. EGR system reduces NOx by recirculating exhaust gases and cooling combustion chambers. To replace EGR valve in gasoline engines, disconnect electrical connector, remove pipe flange and bolts, and clean mounting surfaces. For diesel engines, remove cover from EGR crossover tube, loosen clamps, remove bolts, disconnect wiring, and replace gaskets. Diesel models may also have an EGR cooler.

To clean the EGR cooler on 6.4L HEMI and diesel models, you need to disconnect the battery cables and drain the cooling system. Remove various components like the air filter housing, turbo outlet tube, alternator, and more to access the cooler. Remove the EGR cooler and discard the gasket. Clean it with hot tap water and a cleaning solution. Rinse, dry, and reinstall with a new gasket.

Oxides of nitrogen, or NOx, are compounds formed in the engine when oxygen and nitrogen mix in the incoming air.

For diesel engines, remove the cover from the EGR crossover tube, loosen clamps, remove bolts, disconnect wiring, pry off the valve assembly, clean sealing surfaces, and replace gaskets. Diesel models may also have an EGR cooler located under the intake manifold or on the exhaust manifold.
